It really sucks to hear this because I've been so pleased with the 3800mAh I bought for my Pre almost 2 years ago. The stock battery never made it past noon, but my 3800 (Mugen) worked from 5am 'til usually after midnight. I kinda assumed that both Seidio and Mugen would be reliable brands. Actually, what brought me here was a search to see if Seidio's battery performance perhaps even had an edge on Mugen's.
Hopefully, the above poster's experience was a fluke, because there's a whole bunch of us out here who rely on long-life batteries and don't give a flying rat's about making our phones thinner. In fact, way back when the "brick" portable cellular first evolved into a smaller phone, decisonmakers somewhere, unfortunately, redirected consumer focus with the shiny distraction of phone size rather than quality. I activated one of my 6-year-old Treos the other day because my android smartphone is turning dumber every day. I don't drop calls ANYWHERE and even use it for texting and internet at 40,000 feet! Try that with a so-called, more "technologically advanced," android, pre, or iphone. How did we consumers let this happen?
If consumers had been given a choice, at the beginning of cell phone evolution, to retain optimal cellphone performance, or to sacrifice some of that quality in order to someday have a phone that fits into that otherwise pointless jeans coin pocket, clearly millions would have opted for function over form. As it is, we're relegated to the back of the bus with the other geeks, poindexters, and troublemakers until the rest of the world wakes up and realizes a portable phone really ought to be, um, completely portable. Not everyone spends their day near electrical outlets and car chargers.
